SPECIFICATION forming part of Letters Patent No. 368,302. dateu August16, 1887.

Application tiled October 23, 1884.

To all whom it may concern:

Be it known that I, JOHN Farmers MUL- LANEY, a citizen of the UnitedStates, residing at Plainville, in the county of Books and State ofKansas, have invented a new and useful Speed-Regulating Machine, ofwhich the following is a specification.

My invention relates to machinery where a steady, regular, or nearlyuniform speed or motion is desired, and where the original or motivepower is not so regular or uniform as required or desired; and theobjects of my invention are, first, to obtain from an irregular motivepower of an ununiform motion a uniform and regular motion, and conductthe latter to the machinery which it is required to be turned oroperated thereby; second, when there is an excess of power, to hold thesame in reserve, to be expended as needed to keep up the requiredmotion.

My invention is especially applicable for manufacturing machinery whendriven by wind-power, but is intended for any power to which it isdesirable to connect it.

I attain the above objects by the mechan ism illustrated in theaccompanying drawings, in which I Figure 1 is a vertical front view ofthe entire machine, (except the head of and a part of the arms of thegovernor.) Fig. 2 is a top view of the machine as it appears entire,with some parts of the frame broken off to admit of a better viewof theparts beneath. Fig. 3 is an exposed view of the three separated parts ofthe springand-ratchet coupling.

Similar numbers and letters refer to similar parts of the machinethroughout the entire descriptipn..a the several views.

In Fig. 3, 1 illustrates a part of spring-and ratchet Coupling, composedof a dish-shaped disk of cast n1etal,and containing four ratchetpawls, aa a a, which catch on and engage four corresponding projections at I) bb in ratchetwhcel 2. .Disk 1 is attached by a key (or otherwise) to thepowershaft 3, and turns ratchet-wheel 2 by means of the ratchet-catchesdescribed above. The ratchet-wl1eel2 is about two inches less indiameter than disks 1 and 4, and serves to connect them. It is attachedto disk 4 by means of a coil-spring, (shown in drawings of disk 4,) oneend of which is fastened to disk 4 at c, and the other end to Serial No.146,342. (No model.)

ratchet-wheel 2 at cl. Ratchetwvhcel 2 has a long hub, which turnsfreely over the ends (not shown) where the two shafts 3 and 5 meet, andassists in keeping them on the same line.

Attached to the left side of the periphery of disk 1 is a broad annularflange, the edge of which passes beneath the edge of a similar flangeattached to the right side of disk 4, and these two flanges and theirrespective disks form a sort of casing for the spring-andratchetcoupling and for concealing ratchetwhcel 2.

The horizontal power-shafts 3 and 5 are separate pieces, which meet inthe thimble or sleeve-like hub of ratchet-wheel 2, and are connected inmotion by the three parts of the spring-and-ratchet coupling by means ofkeys in the hubs of disksl and 4t. )Vhen the speed of disk 1 slackensmore than can be compensated by thespring e, the power reserved in theflywheel 6 will tend to carry the machinery on shaft 5, which will bethen disconnected from the power-shaft 3 by means of the ratchetpawls aa a a, which will slip back on ratchetwheel 2 without materiallyretarding the motion of shaft 5. On shaft 5 is along conepulley, 7,connected to its mate or opposite conepulley, 8, by a cross-belt. 9.

in going from pulley 7 to pulley 8 and back the belt 9 passes onopposite sides of a vertical roller, 10, which is intended to force thebelt 9 to the right or left, accordingly as the velocity increases ordecreases. These conepnlleys with the vertical roller, all connected bybelt 9, substantially as set forth in the accompanying drawings, areamong the chief features of my machine. Then the belt 9 is mot ed to theright, pulley 7 may increase its number of revolutions per minutewithoutincreasing the revolutions per minute of pulley 8, and if thebelt 9 is carried to the left the velocity of pulley 7 maybe decreasedwithout decreasing the velocity of pulley 8. Thus, though the velocityof pulley 7 may vary to nearly twice its usual velocity, the velocity ofpulley 8 may be maintained uniform if the belt 9 be moved as describedabove.

The vertical roller 10 is supported on a suspended carrier, 11, which isitself supported on the two opposite squares 12 and 13, as

plainly shown in Fig. 1. This carrier 11, thus suspended, moves with theslightest possible friction, and at the same time secures to the roller10 its proper line of direction between the'two large pulleys 7 and 8.

A pulley, 14, is made to turn by the belt 15. On the same upright shaft.and turning w th it, is smaller cone-pulley 16, Fig. 1, runn nga belt,17, which, passing on either side or a horizontal roller, 18, turnsanother small conepulley, 19, which is the mate or opposite of pulley16. On the same upright shaft with pulley l9, and turning with and byit,is a common centrifugal governor, 20, of which 21 21 are thecentrifugal weights and 22 22 22 22 the connecting-rods and weight-rods.and 23 is the governor-slide, which is connected with the lever 24,which is a simple right-angled lever of the first class, of which 25 isthe power end, 26 is the self-adjusting fulcrum, which movesautomatically to the right and left to maintain a certain distancebetween it and the governor-slide 23, although the distance betweenfnlcrum 26 and the upright shaft, upon which the slide 23 works, willnot always be the same, but variable, and 27 is the end which moves theweight, which is the connectingpiece 28, which moves the suspendedcarrier 11, supporting the vertical roller 10, substantially as setforth above, and illustrated in the accompanying drawings.

It is plain that an increase in the velocity of shaft 5 increases therevolutions of pulleys 14, 16, and 19, and the speed of the weights willtend to raise them,which raises the slide 23, thus raising the lever-arm25 and moving the lever-arin 27 to the right, and drawing withit, bymeans of-the'rod 28, the carrier 11 and roller 10, thus moving the belt9 to the right, and,though pulley 7 has increased ifs velocity and thefiy-wheel 6 has re ceived a greater momentum, thespeed of pulley 8 hasnot changed,nor that of pulley 29, carrying the belt 30, which is togive the power to the machinery proper.

If the speed of pulley 29 is wished to be increased without changing theaverage speed of shafts 3 and 5 and pulley 7, the lever 31 is raised, bywhich means the horizontal roller 18 will be raised, elevating the belt17 to a smaller surface on the cone-pulley 16 and to a larger surface onits mate, (conapulley 19,) and thus though' the velocity of pulley 16 bethe same as formerly, yet the velocity of pulley 19 will be reduced,allowing the weights 2L 2] to lower the slide 23, thus forcing leverarm27, connecting-rod 28, carrier 11, and roller 10 to the left, carryingthe belt 9toward the larger end of pulley 7, and although pulley 7revolves no faster than formerly, yet belt 9 goes much faster, becauseof the increased surface over which it must travel in the same time, andpulley 8 is caused to go still faster, because of the increased velocityof the belt 9 and the decreased size of the pulley 8 near the left end,thus increasing the number of revoshaft 3, and having ratchet-pawls a aa a, in

combination with ratchet-wheel 2, provided.

with four projections, 12 b b, that engage ratchetpawls a a a a,substantially as described.

2. In speed-regulating machines, the combination, with disk 1, providedwith ratchetpawls a a a a, and having a broad annular flange projectingfrom the left side of its periphery, and ratchet-wheel 2, provided withprojections b b b, and a long sleeve-like hub working freely over theend of shafts 5 and 3, of the dish-shaped disk 4 and a large coiledspring attached to disk 4 at c and to ratchetwheel 2 at d, substantiallyas described, and for the purposes set forth.

3. In a speed-regulating machi ne,thespringandratchet couplingconsisting of disks 1 and 4 and ratchet-wheel 2, and the coiled springand ratchet-pawls, substantially as described and illustrated.
